Aqua-bis(1H-benzimidazole-2-carboxyl-ato-?O,N)zinc(II).

ABSTRACT: In the title compound, [Zn(C(8)H(5)N(2)O(2))(2)(H(2)O)], the Zn(II) ion is coordinated in each case by a carboxyl-ate O atom and an imidazole N atom from two different benzimidazole-2-carboxyl-ate (BIC) ligands and one water O atom in a trigonal-bipyramidal geometry. In the complex mol-ecule, the two benzimidazole planes are twisted, making a dihedral angle of 55.93?(11)°. The three-dimensional framework is organized by inter-molecular N-H?O hydrogen bonding and O-H?O inter-actions and ?-? inter-actions between adjacent benzimidazole rings [centroid-centroid distance = 3.586?(3)?Å].

Project description:In the mononuclear title compound, [Co(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)]·2C(3)H(7)NO·2H(2)O, the Co(II) atom, which lies on a center of inversion, is coordinated by four water mol-ecules and two N atoms from two two symmetry-related 1H-benzimidazole-5,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry.

Tetra-aqua-bis(3-fluoro-pyridine-4-carboxyl-ato-?N)zinc(II) dihydrate.

Project description:In the title compound, [Zn(C(6)H(3)FNO(2))(2)(H(2)O)(4)]·2H(2)O, the Zn(II) atom is octa-hedrally coordinated in a ZnO(4)N(2) environment by two 3-fluoro-pyridine-4-carboxyl-ate (3-fpy4-cbx) ligands and four water mol-ecules. The [Zn(3-fpy4-cbx)(2)(H(2)O)(4)] mol-ecules form a three-dimensional network through strong O-H?O and weak O-H?F hydrogen bonds between 3-fpy4-cbx and water mol-ecules. The crystal used for data collection was a twin, with the twin law corresponding to a 180° rotation about the real-space [001] axis. The major twin fraction refined to 0.795?(1).

catena-Poly[zinc(II)-?-aqua-?O:O-bis-(?-quinoline-4-carboxyl-ato-?O:O')].

Project description:The asymmetric unit of the title complex, [Zn(C(10)H(6)NO(2))(2)(H(2)O)](n), consists of one quinoline-4-carboxyl-ate anion, half of a Zn(2+) cation and half of a coordinated water mol-ecule. The cation and the water O atom have crystallographically imposed inversion and twofold rotation symmetry, respectively. The metal centre displays an elongated ZnO(6) octa-hedral coordination geometry provided by the O atoms of four anions at the equatorial plane and two axial water mol-ecules. Each anion and water mol-ecule act as bridges between Zn(II) cations, forming a polymeric chain parallel to [001]. The chains are further linked into a three-dimensional framework through O-H?N hydrogen bonds.

Project description:In the title complex, [Zn(C(10)H(12)NO(2))(2)(H(2)O)]·H(2)O, the Zn(II) ion is coordinated by two N and two O atoms from two 5-n-butyl-pyridine-2-carboxyl-ato ligands and one O atom from a water mol-ecule in a distorted square-pyramidal geometry. In the crystal, inter-molecular O-H?O hydrogen bonds link mol-ecules into a two-dimensional supramolecular structure parallel to (001).

Poly[[(?-1H-benzimidazole-5,6-dicarboxyl-ato)zinc(II)] monohydrate].

Project description:The three-dimensional polymeric title compound, {[Zn(C(9)H(4)N(2)O(4))]·H(2)O}(n), contains one crystallographically independent Zn(II) atom, one fully deprotonated 1H-benzimid-azole-5,6-dicarboxyl-ate (bdc) ligand and one uncoordinated water mol-ecule. The Zn(II) atom is four-coordinated by three O atoms and one N atom from the bdc ligands, giving a distorted tetra-hedral coordination geometry. The uncoordinated water mol-ecule is bound to the main structure through a strong bdc-water N-H?O hydrogen bond, and two much weaker water-bdc O-H?O inter-actions.

Di-?-acetato-?-aqua-bis-[acetatobis(1H-benzimidazole)cobalt(II)].

Project description:In the title compound, [Co(2)(C(2)H(3)O(2))(4)(C(7)H(6)N(2))(4)(H(2)O)], the half-mol-ecule in the asymmetric unit is completed by a crystallographic twofold rotation axis to give the full mol-ecule. The Co(II) ions are approximately octahedrally coordinated with a cis-N(2)O(4) coordination sphere. The compound features intra-molecular O-H?O hydrogen bonds between the non-bridging acetate groups and the bridging water mol-ecule, and inter-molecular N-H?O hydrogen bonds between the acetates and amine H atoms of the benzimidazoles which determine the mol-ecular packing in the crystal structure.

Guanidinium hexa-aqua-zinc(II) bis[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate].

Project description:In the title mol-ecular salt, (CH(6)N(3))(1.30)[Zn(H(2)O)(6)](0.35)[Zn(C(7)H(4)NO(4))(3)](2), the Zn(II) atom (site symmetry 3) in the anion is coordinated by three N,O-bidentate 3-carb-oxy-pyridine-2-carboxyl-ate monoanions to generate a fac-ZnN(3)O(3) octa-hedral coordination geometry. The guanidinium cation (the C atom has site symmetry 3) and the octa-hedral hexa-aqua-zinc(II) dication (the Zn(2+) cation has site symmetry -3) are occupationally disordered in a 1.30:0.35 ratio. In the crystal, the components are linked by O-H?O and N-H?O hydrogen bonds to generate infinite (001) sheets. Weak aromatic ?-? stacking [centroid-centroid distance = 3.797?(8)?Å] is also observed in the crystal.
